But if you don't want to run 2.6.32 permanently/on your live system,
iirc you can just run it to do the migration, and once the migration and
reshape have completed, you can go back to your production kernel.
Having said that, 2.6.22's a bit old and I don't see it listed on
Gentoo's package web site, so you might think of updating to something
more recent anyway.
Cheers,
John.
